half to reg., assignor of one- Application February 10, 1947, Serial No. 727,529 3 Claims. (Cl. 229-45) This invention relates to covers for boxes and particularly boxes made from cardboard or the like.

The primary object of the invention is to provide a cover or lid for boxes of the cardboard type that can be easily opened for inspecting the contents of the box. This is particularly important in the inspection of apples and the like wherein it is necessary to open the lid and reclose the same at the time Of inspection.

With my new and improved cover and lid construction I provide a keeper on the upper front side of the box into which the tongue of the lid of the box is inserted. lhis keeper holds the tongue of the lid securely in place against the side of the box and at the same time reinforces the box relative to the lid.

Further, I provide means associated with the keeper and the tongue of the lid to lock the said tongue of the lid within the keeper.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a perspective view of a conventional type of cardboard box showing the lid in open position.

Figure 2 is a perspective view of Figure 1 showing the lid in closed position.

Figure 3 is a fragmentary detailed sectional view taken on line 3-3 of Figure 1, illustrating the tongue of the lid inserted under the keeper and being locked thereunder by a special locking tab.

Figure 4 illustrates a modified form of this invention.

Figure 5 is a fragmentary horizontal sectional view of another modification of this invention.

In the drawings:

A conventional cardboard box is indicated at I, although I do not wish to be limited to the material from which the box is made, but my invention is most admirably adapted to be used in connection with boxes that are made from a flexible material other than wood or the like. My invention consists of securing to the side 2 of the box a keeper or bar 3. This keeper is secured to the box by suitable fastening means, as rivets 4.

In the operation of the lid a tongue 5, forming part of the lid 6, is inserted between the side wall 2 of the box and the keeper 3, as best illustrated in Figures 2 and 3. Any method may be used to lock the tongue 5 within the keeper, as for instance the tab 1 which may be secured by any means to the keeper bar 3, as by the rivet 8. A slit or hole 9 is formed within the tongue 5 and when the tongue is inserted to the position shown in Figures 2 and 3, the tab 1 is inserted through the hole 9. This tab holds the tongue down in place and prevents the same from being withdrawn from the keeper.

I have illustrated another method of locking the tongue in place in Figure 4 where the tongue is notched at It], and as the same is inserted within the keeper the portion Ii may be bent outwardly as indicated by the dotted lines, thereby preventing the tongue from being withdrawn from under the keeper bar 3.

In Figure 5 the locking bar 3a which is secured to the front wall 5a by rivets or fastening means 4a, is adapted to be bent outwardly when the tongue 9a is inserted. The tongue 9a is of such width as to frictionally bind at the opposite edges thereof, as indicated at l2, between the keeper bar 3a and the front wall 5a. In this manner the tongue 9a will be frictionally locked in lid closing position.

With my new and improved lid construction it is possible to quickly and easily inspect the contents of the box without in any way destroying the same. The locking means relative to the tongue of the lid is disengaged and the tongue is then withdrawn from between the keeper and the side of the box allowing access to the box and the same can be readily closed after inspection, which is the primary object of my invention.

I do not wish to be limited to the exact mechanical structure as mechanical modifications may be made still coming within the scope of my claims.

What I claim is:

1. In a box having a hinged lid, a transversely elongated tongue formed along the front edge of said lid, a transversely elongated keeper bar extending across the front wall of the box and secured thereto adjacent the opposite ends of said front wall, said tongue being adapted to extend downwardly between said bar and said front wall substantially along the entire length thereof and be frictionally held thereby, and operatively engageable means on said tongue and said bar adapted to prevent upward movement of said tongue relative to said bar.

2. In a box having a hinged lid, a transversely elongated tongue depending from, and extending the length of, the front edge of said lid, a keeper bar extending transversely across the front wall of the box and secured thereto adjacent the opposite ends of the latter, said tongue being adapt ed to extend downwardly between said keeper bar and said front wall when said lid is in closed position, a transverse slot formed through said tongue and disposed below the bottom edge of said bar when said lid is in said closed position, and a locking tab depending from said bottom edge and adapted to extend into said slot and between said tongue and said front wall for looking said tongue against upward movement relative to said bar.

3. In a box having a hinged lid, a transversely elongated locking tongue carried by the front edge of said lid, an elongated keeper bar, means securing said bar to the front wall of the box in a position whereby said tongue may be extended between said bar and said front wall, and a locking tab carried by at least one edge of said tongue and bendable outwardly at a point below said bar to thereby lock said tongue in lid closing position.
